RUBBER HEEL.

Specification of Letters Patent. Patented Aug. 24, 1920.

Application filed January 3, 1919. Serial No. 269,497.

T 0 all whom t may concern:

Be it known that I, JOHN R. Pn'r'rrr, a citizen of the United States, and resident of 556 W. 186th St., New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Rubber Heels, of which the fol perspective view of the heel in place on a shoe, Figs. 2 and 3 show in perspective, the component parts of this invention and Fig. t is a detail, in section, showing the. method of attachment.

For reasons of economy in rubber, this `heel is adapted to cover only a portion of the shoe heel. In the application as shown in Fig. 1, the rear portion of the heel 10 of the shoe 11 is removed to make room for the rubber heel 13 which is placed flush with the tread of the heel at 12.

The heel consists of a segment of rubber 21 inclosed within a metallic casing similar to Fig. 2 and secured in place by three nails 25, as indicated, to the heel proper. The holes 17 in the wearing side of the casing or armor 14 are larger than the heads of the nails 25, allowing these heads to pass through and engage a washer 23 which securely holds the rubber 21 and the underside 15 0f the metallic casing.

This construction, it will be observed', provides a free metallic outer cover or armor for the wearing surface of the rubber which is not secured to the rubber but is free to move independently thereof. This metallic cover is preferably made from spring steel with a bias to rest upon the rubber so that it readily responds to the resiliency of the latter. If this cover were rigidly ser. cured upon the top of the rubber it would compress the latterv and, to alarge` extent destroy its resiliency, besides, the wearing away of the nail heads would destroy the attachment.

I wish it. to be understood that the principle of the present invention may bevapplied in different ways to secure a free metallic cover over a cushion of rubber other than those illustrated.

It is observed that one portion of a heel, generally the back, is worn away first, I therefore provide a rubber ledge at this point 22, with a corresponding cut-away section of the metallic cover as at 18, Fig. 2. This leaves the rubber flush with the surface of the heel and this condition is maintained as the heel wears away, the line of wear being indicated by the dotted line c-0Z. The armor gradually wears away exposing a greater surface of rubber as the heel is Worn down.

The contour of the metallic plate 14, is preferably made slightly smaller than the shoe heel as indicated at 30, Fig. 1, this enables the rubber to be readily trimmed down flush with the edge of the heel with an ordinary trimming knife.

This heel presents a combination of me` tallic, rubber and leather members engaging the ground rendering it less liable to slip on wet aavements. The vacuum or suction e ect produced by rubber heels is largely eliminated and it does not offer an (fibstruction to placing garments over the oot.

Having thus described my invention, I claim:

1. In a shoe heel, the combination of a resilient member, a U-shaped metallic plate, said plate substantially covering said member, and nails for securing said resilient member, the outside of said U-shaped plate provided with holesv to allow the heads of said nails to pass through.

2. In a shoe heel, in combination, a resilient member, a U-shaped metallic plate enclosing said member, and means passed through the outside of said plate for securing said plate and said member to said heel.

Signed at 76 William street, New York city, in the county of NewYork and State of New York this 14th day of December A. D.
